Disodium C12-14 Pareth-2 Sulfosuccinate

INCI: DISODIUM C12-14 PARETH-2 SULFOSUCCINATE

A gentle, low-irritation surfactant that cleans without stripping the skin, ideal for sensitive or dry skin types.

In plain English

This ingredient is a mild soap-like molecule that helps water mix with oil and dirt so they can be rinsed away. Unlike harsher detergents, it is less likely to leave your skin feeling tight or dry. It is often used in 'gentle' or 'sensitive skin' cleansers because it cleans effectively without over-stripping your skin's natural moisture barrier.

Quick decision guide

Useful, but context matters

Disodium C12-14 Pareth-2 Sulfosuccinate is generally a lower-concern ingredient when the full formula suits your skin.

Plain-English read

Treat this as a practical screening step before you compare products that contain this ingredient.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Disodium C12-14 Pareth-2 Sulfosuccinate.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.

Score terms in plain English

Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

There is useful support, but formula details and claim strength still matter.

What it is

Disodium C12-14 Pareth-2 Sulfosuccinate is a semi-synthetic surfactant made by combining fatty alcohols from coconut oil with sulfosuccinic acid. It belongs to the sulfosuccinate family, known for being exceptionally mild on skin and eyes.

How it works

In a cleanser, this molecule has a water-loving head and an oil-loving tail. When you lather it with water, the tails grab onto oil, dirt, and makeup, while the heads stay in the water. Rinsing then washes everything away. Its large molecular structure makes it less penetrating and therefore less irritating than smaller, harsher surfactants like sodium lauryl sulfate.

Pros

Very gentle on skin

Its large molecular structure means it sits on the surface of the skin rather than penetrating, which significantly reduces irritation and dryness compared to harsher detergents.

Mild foaming action

It produces a soft, creamy lather that feels pleasant on the skin without the tight, squeaky-clean feeling that can signal over-stripping.

Cons and cautions

Less effective on heavy makeup

Because it is so mild, it may struggle to fully remove long-wearing or waterproof makeup on its own, often requiring a double-cleansing step.

Semi-synthetic origin

It is not a fully natural ingredient; it is chemically modified from natural sources, which may be a concern for those seeking 100% natural formulations.

Best for

  • People with dry or sensitive skin
  • Those looking for a gentle daily facial cleanser
  • Anyone who finds traditional foaming cleansers too harsh

Use caution if

  • Individuals with known sulfosuccinate allergy (rare)
  • Those who prefer completely natural, plant-only ingredients (this is semi-synthetic)

Usage tips

Use in a gentle foaming cleanser for daily morning or second-step cleansing.
Pair with an oil-based cleanser or micellar water first if you wear heavy makeup or sunscreen.
Look for formulas that combine it with other mild surfactants for a balanced clean.

Safety summary

Disodium C12-14 Pareth-2 Sulfosuccinate is considered safe for use in rinse-off cosmetics at typical concentrations. It has a low irritation and sensitization profile, making it suitable for sensitive skin. No significant safety concerns have been raised by regulatory bodies.

Research notes

Research on sulfosuccinates consistently shows they are among the mildest anionic surfactants, with low skin and eye irritation potential. Studies indicate they cause less protein denaturation and lipid extraction from the skin compared to sodium lauryl sulfate.

Common label clues

Typical concentration
1% to 10% in rinse-off products
Regulatory status
Approved for use in cosmetics by the FDA and the European Commission. The Cosmetic Ingredient Review (CIR) panel has deemed sulfosuccinates safe as used in rinse-off products.
Common uses
Facial cleansers, Body washes, Shampoos, Baby care products
Environmental note
Sulfosuccinates are generally considered biodegradable, but their production involves chemical processing. Always check the brand's overall environmental commitments.

Good to know

  • It is often used in baby shampoos because of its low eye-sting potential.
  • On an ingredient label, it may appear alongside 'cocamidopropyl betaine' to boost mildness and foam quality.
